Arboricultural Impact Assessment (AIA)

PLANNING & DEVELOPMENT

What is an Arboricultural Impact Assessment ?

An arboricultural impact assessment may be required as part of a planning application relation to a site that is close to, or contains trees

This assessment of tree health details the potential impact a construction project may have on the surrounding trees, as well as the impact the trees will have on the finished structure.

Arboricultural Impact Assessments contain an appraisal of the pre-construction situation on the site. This includes an assessment of tree quality in accordance with British Standard BS5837:2012, taking into account the trees’ individual arboricultural, landscape and cultural or ecological values and their estimated remaining contribution. Detailed information on all surveyed trees is available in the Tree Survey Schedules, which are included in the report. Urban Tree Managements Arboricultural Impact Assessments also include recommendations for:

• Remedial health and safety tree works.
• Guidance on which trees may be retained given the proposed site layout.
• Protection measures to be implemented during construction.
• Guidance on specialist construction methods for structures in close proximity to trees.
• Guidance on mitigation for tree removal and recommended planting specification.
• Suggestions for future arboricultural management to maximize the safe useful life expectancy of retained trees.

Urban Tree Managements reports are professionally presented and are accompanied by both Tree Constraint Plans and Tree Protection Plans. Clearly presented drawings and comprehensive reports will increase the chances of planning permission being granted.
